AISI COLD-FORMED STEEL DESIGN MANUAL, CHANGES IN ALLOWABLE LOAD CALCULATIONS

The beam and column loads given in this catalog are based on the 1996 edition of the AISI Cold-Formed Steel Design Manual.

Since the issuance of the first Nuclear Power Engineering Catalog (NE-1), the AISI Engineering Committee had continued to alter and modify the formulae for calculating allowable loads. Therefore, loads in the catalog may be different from those in the NE-1.

Unistrut’s products for the nuclear industry have not decreased in strength. The materials and processes used to manufacture Unistrut nuclear products remain the same as they were for NE-1. However, the AISI formulae for allowable loads has changed.

As a leader in the nuclear industry for strut products, we believe that adhering to the latest engineering design standards for cold-formed steel is imperative. This catalog represents those latest design standards.

ASTM A 1011 STANDARD VS. ASTM A 570 STANDARDIn 2000, ASTM discontinued specification ASTM A 570 and replaced it with ASTM A 1011. Unistrut completed an engineering review of the two specifications and concluded that the chemical and mechanical properties of A 1011 SS Grade 33 are the same as A 570 Grade 33. Unistrut reserves the right to certify parts made from ASTM A 570 Grade 33 to ASTM A 1011 SS Grade 33.

N1000® SERIES CHANNEL & COMBINATIONS


®

FRAMING MEMBERS

Unistrut channels and continuous inserts are accurately and carefully cold-formed to size from low carbon strip steel. One side of the channel has a continuous slot with inturned edges. Secure attachments may be made to the framing member with the use of hardened, toothed, slot-ted nuts which engage the inturned edges.

Raw steel shall conform to the following specifications.

FITTINGS

Unistrut fittings, unless noted otherwise, are punch-press made from hot rolled, pickled and oiled steel plates, strip, or coil and conform to ASTM specifications A575, A576. The fitting steel also meets the physical requirement of ASTM A1011SS GR 33. The pickling of the steel produces a smooth surface free from scale.

NUTS AND BOLTS

Unistrut nuts are made from steel coils or bars. After all machining operations are complete, they are thoroughly case hardened. Nuts are rectangular with ends shaped to permit a quarter turn clockwise in the framing member after insertion through the slotted opening in the channel. Two toothed grooves in the top of the nut engage the in-turned edges of the channel and, after bolting operations are completed, will prevent any movement of the bolt and nut within the framing member. All bolts and nuts have Unified and American coarse screw threads. The standard framing nut is 1⁄2” and conforms to ASTM Specification A576 GR 1015 (modified). Machine screws & hex head screws conform to SAE J429 GR 2 (also meets and exceeds ASTM A307).

FINISHES

PERMA-GREEN® II (GR)Channel and parts are carefully cleaned and phosphated. Immediately after phosphating, a uniform coat of a highly effective rust-inhibiting acrylic enamel paint is applied by electro-deposition and thoroughly baked. Color is Perma-Green per Federal Standard 595a color number 14109 (dark limit V-). The resulting finish will withstand 400 hours of salt spray when tested in accordance with ASTM designa-tion B-117.

ELECTRO-GALVANIZED (EG)Parts, screws and nuts are coated with zinc electrolytically to commercial standards (ASTM - B633 Type III SC1).

PRE-GALVANIZED (PG)Material (steel strip) is coated with zinc by hot-dip process prior to roll-forming or press operations. The zinc coating weight is G90 conforming to ASTM Specification A653 GR 33.

HOT-DIPPED GALVANIZED (HG)Material is coated with zinc after being roll-formed or after all manufacturing operations are completed, conforming to ASTM specification No. A123 for large items and A153 for centrifuged parts such as fasteners & small fittings.

SPECIAL METALSUnistrut channel is also available in stainless steel per ASTM A240 (Type 304). Contact Unistrut for details.

Notes: 1. Above loads include the weight of the member. This weight must be deducted to arrive at the net allowable load the beam will support. 2. Long span beams should be supported in such a manner as to prevent rotation and twist. See Page 16 3. Allowable uniformly distributed loads are listed for various simple spans, that is, a beam on two supports. If load is concentrated at the center of the span, multiply load from the table by 0.5 and corresponding deflection by 0.8. 4. Column loadings are for allowable axial loads for the unsupported heights listed with a K value of 0.80.

MATERIAL

Unistrut spring or springless nuts are manufactured from mild steel bars, and after machining operations are com-pleted, they are case hardened. Hardening assures posi-tive biting action into the inturned edge of the Unistrut channel. Nuts, bolts & washers are electro-galvanized, unless otherwise noted.

THREADS

All threads on the nuts & bolts are Unified & American screw threads, UNC classes 2A & 2B. The threads on Unis-trut nuts are accepted at .002” over the 2B maximum limit.

EXAMPLE IPROBLEM:Determine load and deflectionof a N1000 beam continuous over one support and loaded uniformly on one span.

SOLUTION:A. From load table for N1000 on page 24 load for a 5’-0” span is 680# and deflection is .35”.B. Multiply by factors from Table above. Load = 680# x 1.30 = 884# Deflection = .35” x .92 = .32”

CONVERSION FACTORS FOR BEAMS WITH VARIOUS STATIC LOADING CONDITIONS

All Beam Load tables are for single-span (simple) beams supported at the ends. These can be used in the majority of the cases.

There are times when it is necessary to know what happens with other loading and support conditions. Some common arrangements are shown below. Simply multiply the values from the Beam Load tables by factors given below

b) Pinned Top – Fixed Bottom

The top is restrained against lateral move-ment (translation) but, is allowed to rotate. The bottom is restrained against rotation and lateral movement. This is a common support condition and is used to con-struct the allowable column load applied at the Slot Face tables. “K” equals .80.

c) Pinned Top – Pinned Bottom

Both ends are restrained against lateral movement (translation) but, are allowed to rotate. “K” equals 1.0.

d) Fixed / Free Top – Fixed Bottom

The top is restrained against rotation but is allowed to move laterally. The bottom is restrained against rotation and lateral movement (translation). “K” equals 1.2.

COLUMN LENGTH

The column length is measured from braced point to braced point. A braced point is where the column is restrained from lateral movement (translation) in all directions.

TYPES OF LOADING

a) Concentric Loading Loads applied to the center of gravity

of the column cross-section are con-sidered concentric. A beam that passes over and rests on the top of a column

is an example of concentric loading.

b) Eccentric Loading Any load which is not concentric is ec-

centric. The amount of eccentricity (in inches) has a major effect on the load-carrying capacity of any particular column. A load that is transmitted to a Unistrut Metal Framing column using a standard fitting bolted to the slot face is considered eccentric.

The load tables give allowable loads for both concentric (loaded at C.G.) and certain eccentric (loaded at slot face) load-ing. Allowable loads for other eccentric loading must be determined by a qualified

design professional.

SUPPORT CONDITIONS

Based on the support conditions, an ap-propriate “K” value is selected. This “K” value, which mathematically describes the column end conditions, is used in the column design equations. The most com-mon support condition combinations are as follows:

a) Fixed Top – Fixed Bottom

Both ends are restrained against rotation and lateral movement (translation). K equals .65.

CROSS-SECTIONALSHAPE

The cross-sectional shape of a column member determines the value of it’s “Radius of Gyration” or “r”. In general, a member with a large “r” makes a better column than a member with a small “r”. Each axis of a column has a different “r”. Typically the axis with the smallest “r” determines the final design.

BOLT TORQUE

Bolt torque values are given to ensure the proper connection between Unistrut Metal Framing components. It is impor-tant to understand that there is a direct, but not necessarily consistent, relation-ship between bolt torque and tension in the bolt. Too much tension in the bolt can cause it to break or crush the component parts. Too little tension in the bolt can prevent the connection from developing its full load capacity. The torque values given have been developed over many

years of experience and testing.

These are based on using a properly calibrated torque wrench with a clean dry (non-lubricated) Unistrut fitting, bolt and nut. A lubricated bolt or nut can cause extremely high tension in the connection and may lead to bolt failure. It must be noted that the accuracy of commercial torque wrenches varies widely and it is the responsibility of the installer to ensure that proper bolt torque has been achieved.
